Section #3 - Test Mode and Instrument Tests
The Test Mode includes 7 options and allows you to verify the TruSpeed's
mechanics. These options include:
• Display Integrity Test

 Fixed Distance Zero Velocity Test

Display Integrity Test
The Display Integrity Test allows you to verify that all display segments are
operating. LTI suggests that you do this test periodically.
1. Ensure that the TruSpeed is powered
ON.
2. Press the button. The display
should look like Figure #23.
 Compare the instrument's LCD
to Figure #23 (A).
 Compare the instrument’s
in-scope Heads Up Display to
figure #23 (B). The lower
portion of the display will flash
5 times. If the display times out
before you can complete this
test, press the button
repeatedly until this screen is
displayed again.
3. If any segment fails to display,
contact Laser Technology, Inc. to
arrange for repair. See the inside
front cover for LTI contact
information.

The display integrity is also tested each time the unit is powered ON.
However, the results are only briefly displayed before the results of the
Self Test are displayed.
